We’ve been climbing Lea Hill roofs since 2016, back when most of these homes were barely ten years old. The neighborhood’s changed since then, but the original roofs haven’t - and that’s the problem. Lea Hill sits on an elevated plateau above the Green River Valley floor, putting it directly in the path of southwest Pacific weather systems with more wind-driven rain exposure than Auburn below. The majority of the neighborhood’s housing stock dates from the 1980s-90s suburban build-out, meaning a large cohort of original 25-30 year composition shingle roofs are at or past their design life simultaneously - creating a wave of full replacements unique to this hilltop community rather than the scattered replacements typical in mixed-age neighborhoods. We know the streets, the builders, the original materials, and what fails first. That matters when you’re deciding whether to patch again or replace once.
Why Ridgeline Roofing Co. of Seattle Is Lea Hill’s Preferred Roof Replacement & Installation Company
Neil Cavanaugh founded Ridgeline Roofing Co. in 1984, and we’ve been serving King and Pierce County homeowners for over 42 years. We’re not storm chasers with out-of-state plates and a P.O. box. We hire local crews, train apprentices into journeymen, and plan to be here in thirty years - the same cannot be said for every contractor who’s knocked on Lea Hill doors after a wind event.
Our reputation here is built on showing up when we say we will and documenting what we find. Our technicians are background-checked, uniformed, and trained to photograph every roof inspection from the actual surface - not the driveway. Lea Hill homeowners see what we see: lifted shingles, compromised valleys, the moss working its way under tabs on north faces. No scary speeches, just photos and straight talk about what needs to happen now versus what can wait.
Phones are staffed by a live person 24 hours a day, seven days a week. Not a voicemail tree. Not “leave a message and we’ll call back Tuesday.” A real human who can dispatch a crew or schedule an inspection. For Lea Hill’s older housing stock, that responsiveness matters - a small leak around a 1988 skylight can turn into ceiling damage fast when the next storm rolls in off the Pacific.
Every job carries our written 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork to file, no arguing, no runaround. We’ve honored that promise for four decades. It’s why neighbors on Lea Hill recommend us to neighbors.
Our Roof Replacement & Installation Services in Lea Hill
Full Roof Replacement
This is what most Lea Hill homeowners need right now. The original three-tab asphalt shingles from the 1980s-90s build-out are failing in predictable patterns: granule loss exposing the fiberglass mat, cracked tabs from thermal cycling, and lifted edges where moss colonies have taken hold. We strip to deck, replace rotted sheathing, install proper underlayment and ice-and-water shield at valleys and penetrations, then finish with a system designed for Western Washington’s wet climate. We replaced a full roof on a 1988 split-level in the Lea Hill Highlands neighborhood where the north-facing slope had thick moss mats that lifted shingle edges, wicking moisture into the OSB deck. During tear-off, we found three full sheets of rotted decking - adding $1,200 to the estimate - and replaced them with new plywood before installing a GAF Timberline HDZ shingle system with ice-and-water shield at all valleys and penetrations. The homeowner’s original quote from a drive-by estimator hadn’t accounted for deck replacement. We build that possibility into every Lea Hill estimate because we’ve learned to expect it.

Asphalt Shingles
For Lea Hill’s standard 4/12 to 6/12 pitch roofs, architectural asphalt shingles remain the practical choice for most homeowners. We install GAF Timberline HDZ, CertainTeed Landmark, and Owens Corning Duration lines - all rated for the wind exposure this plateau sees. A typical 2,000-square-foot Lea Hill home runs $12,000-$18,000 for a full asphalt shingle replacement including tear-off, deck repair as needed, and disposal. The upgrade from three-tab to architectural adds roughly $1,500-$2,500 but buys you a 50-year product with better wind resistance and dimensional appearance. Given Lea Hill’s exposure, we rarely recommend three-tab for replacement anymore.

Metal Roofing
Metal roofing is gaining traction on Lea Hill for good reason. Standing seam systems shed moss and debris better than shingle roofs, and their interlocking panels handle wind-driven rain more effectively than any exposed-fastener system. For homeowners planning to stay twenty-plus years - which describes most of our Lea Hill callers - metal’s 40-70 year lifespan changes the math. A typical Lea Hill home runs $22,000-$35,000 for standing seam aluminum or steel, though complex rooflines with dormers and skylights push toward the higher end. We install Atlas and Tamko metal products with proper ventilation details, critical on Lea Hill’s older homes that weren’t originally designed for the condensation management metal requires.

New Construction
While Lea Hill’s build-out is largely complete, we do handle select infill and major renovation projects where the original structure is expanded or reconfigured. Our Roof Replacement & Installation team coordinates with framers and general contractors to ensure proper valley drainage, adequate intake and exhaust ventilation, and ice-and-water shield placement that meets current code - all lessons learned from decades of fixing what 1980s builders got wrong.

Stocking common colors and accessories locally means most Lea Hill jobs start within a week of approval, not after a three-week special order delay.
Common Roof Replacement & Installation Problems We See in Lea Hill Homes
- Moss-hidden deck rot on north-facing slopes. Western Washington’s persistent cloud cover keeps Lea Hill’s north and west roof faces damp for months, accelerating moss growth that lifts shingle edges and wicks moisture into OSB decking. The rot spreads silently until tear-off reveals full-sheet deterioration, routinely adding 20-30% in decking costs to estimates that looked straightforward from street level.
- Original three-tab shingle failure across the plateau. The 1980s-90s build-out used 20- or 25-year three-tab composition shingles now well past design life. Granule loss exposes the fiberglass mat to UV breakdown; cracked tabs create direct water paths. On Lea Hill, this failure pattern is neighborhood-wide, not isolated, because the housing stock aged together.
- Wind-driven rain infiltration at skylights and dormers. Lea Hill’s elevation and open exposure mean rain hits harder and at steeper angles than in sheltered valley communities. Aging flashing around the numerous skylights and dormers common to 1980s-90s designs lifts and separates, allowing water behind the finish materials where it damages interior ceilings and walls.
- Inadequate original ventilation accelerating shingle degradation. Many Lea Hill homes were built with minimal soffit intake and no ridge exhaust, creating attic heat and moisture buildup that cooks shingles from below while moss attacks from above. Proper replacement includes balanced ventilation, not just new surface materials.

FAQs - Roof Replacement & Installation in Lea Hill
Moss damage routinely adds 20-30% to Lea Hill replacement estimates due to hidden OSB deck rot discovered during tear-off. The moss mats lift shingle edges and hold moisture against the decking for months, causing deterioration that isn’t visible from the ground or even from a ladder inspection. We build potential deck replacement into every Lea Hill estimate so you’re not caught off-guard. Call (866) 850-9676 for a free inspection and exact quote.
If your three-tab roof is original to a 1980s-90s Lea Hill home, replacement is almost always the better investment. These shingles are past design life, and patch repairs on failing widespread material waste money you’ll spend again within a few years. A full replacement with modern architectural shingles or metal gives you 30-50 years of service and eliminates the cycle of chasing leaks. We offer free second opinions on any written estimate if you want confirmation.
Lea Hill’s elevated plateau sits directly in the path of southwest Pacific storm systems, while Auburn in the Green River Valley below has more shelter from terrain and tree cover. The wind hits Lea Hill harder and at angles that drive rain under shingle tabs and aging flashing, especially around skylights and dormers common to the neighborhood’s 1980s-90s designs. This exposure difference is real and measurable - we’ve replaced valley underlayment on Lea Hill homes that was still sound on identical Auburn houses built the same year.
Metal roofing performs exceptionally well on Lea Hill. Standing seam panels shed moss naturally, resist wind-driven rain better than any shingle system, and handle the plateau’s exposure without the degradation that shortens asphalt life. The upfront cost is higher - typically $22,000-$35,000 versus $12,000-$18,000 for asphalt - but for homeowners staying twenty-plus years, the lifecycle cost often favors metal. Proper ventilation installation is critical; we address this on every Lea Hill metal job.
Check your gutters and downspout exits for granule accumulation - heavy loss indicates shingle breakdown. Look for lifted, cracked, or missing tabs, especially on west and south faces that took the storm’s direct hit. Interior signs include water stains on ceilings near skylights or dormers, and musty attic smells indicating moisture intrusion. If you see any of these, call (866) 850-9676. We answer live 24/7 and can inspect within 24 hours to document storm damage for insurance if replacement is warranted.
